mRovnnmNT IN 'cuLTIvA'roRs The Schedule referred in these Letters Patentand.' making part of the same.

To all whom fit may concern:

Beit known that 1, GARLAND B.Y Sr. JOHN, of Brooklyn, vvin the county ofJackson, and State of Michigan, have invented a new and improved Sulky-Cultivator; and I do hereby declare that the following is a full, clear,and exact description thereof,which will enable those skilled in the artto make and use the same, reference being had to the accompanyingldrawings, forming part of this specitication-` This invention relates toa new and improved means v for regulating the depth of the penetrationof the shovels in the earth, and also for raising the same, in order toclear obstructions; and also in an improved way of l bracing thestandards, so as to prevent the same from clogging or choking up withweeds, trash, 85e., and preserve them from lateral strain.

The object of theinvention is to obtain a sulky-c ul tivator which willpossess the advantages above-stated, together with simplicity andeconomy in construction, durability, and eas'e of draught.

In the accompanying sheet of drawings- Figure l is a side sectional viewof my invention, taken in the line :t x, iig. 2.

Figure 2, a plan or top view ofthe same.

Similar lett'eis'of reference indicate corresponding parts.

The central -beam A of the frame of the machine constitutes the rearpart ofv the draught-pcle, and the rear bar u,'of the frame, is attachedcentrally to the rear end cf A, and vis secured at each end, by clips bl, to the rear ends of oblique bars c c, which form the side pieces ofthe frame, the 'ont of the frame being composed of two bars, di (l,placed one above the other, and bolted to the` upper and under side ofthe beam A, the front ends of the side bars c c being secured betweenthem.

B is the drives seat, which is attached to the outereuds of bars e c,the'- iuner ends of the latter being se cured to the beam A.

AThe drlver's seat is a considerable distance from the rear of theframe, in order that aproper eqnipoise may be obtained.

C C represent two plow-beams, the 4front ends of which are connected, byjoints or hinges f j, to the front part of the frame, said jointsadmitting of the plow-beams working up and down.

lI'hese plow-beams are connected, by chains g g, with levers D D, thefront ends of which are connected, by joints h, to the front part of theframe; said levers extending back Within convenient reach of the driverAon seat B.

When these levers are raised so as to restrupon uprigllt's'a i, on theframe, the plows or shovels Will be out of the ground; and the plows orshovels will work in the ground when the levers restuppn the top of theframe.

To each beam C there are attached two standards E E', one standard beingin advance of the other, the front standard, E, being at the inner, andthe'rear standard at the outer side of the beams. (See iig. 2.)

These standards are attachedy to the beams by bolts j, which passthrough arms It,Av the latter causing the standards to be at a suitabledistance dem the beams;

and each bolt j secures a brace, AX, to' the beams,

which braces hold the standards at a greater or less angle ofinclination, as may be desired.

The braces are attached to the standards by joints '1, and by looseningthe bolts j the braces may be adjusted so as'to give the standards theproper degree of inclination.

By this arrangement, the depth of the penetration of the shovels orplows may be regulated as desired, and the standards are well' braced,so as to resistlateral strain.

F arethe plows or shovels, attached to the lower ends of the stands.They may be constructed in the usual or any proper manner. p Y

-G is a standard, which is attached to both plowbeams, by a bolt, on,.which passes through .the arms n n and both beams C O, so as tobringsaid standard at the centre of the machine.

This standard is braced by rods H H, the iront ends of which areconnected to it by jointso o, and the rear ends connected to the undersides of the beams 'C G, by bolts p, which pass through oblong slots inthe beams, to admit of the adjustment of the standard to a greater orless angle of inclination, as desired.

The standard G also has a plow or shovel, F', se-

cured toits lower end, and" the shovels oi' the standards E may, by theinsertion of bevel washers behind them, be inclined either to the rightor left, so as to throw the' earth towards or om the growing plants, asrequired.

There is no opportunity for rubbish to collect and choke up the plows orshovels, owlng to free or open space allowed underneath the machine, andthe plowbeams are allowed an ample rising and falling movement, so thatthey may-be raised as high as desirable in any instance.

'I claim as new, and desire t'o secure by Letters Patent?- Y Thesecuring of the standard Gr between the two beams C G, by means of thebolt m,arn1s n n, and

braces H H, all arranged substantiallyas and for the purpose set forth.

The above specilicatiou of my invention signed by me, this 28th day ofApril, A. D. 1868. GARLAND B. ST. JOHN.
